Failed update prevents further updates

[filipesilva]

This issue impacts 9.0.0-rc.0 and happened while updating https://github.com/vmware/clarity.

After a failed update such as described in #16019, the project will have already been updated to the latest versions.

Attempting to update again will inform the user that everything is up to date.

$ ng update @angular/cli @angular/core --next --force

This is inaccurate as the update did not actually complete successfully. To redo the update, a user will have to manually undo commits and reinstall packages, and only then will they be able to attempt to update again.
